Do you know how to work with the source editor? If so, here's the source code for the UnderstudyInfo-Infobox:

otherwise, on the righthand side of the editing field, if you scroll down, there is a "Template" title. If you expand that, then click on "Add other template". After that, search for "UnderstudyInfo", and fill out the fields that show up, and there you go~
